#8728 closed Bug (invalid)

Character count does not work in CKEditor for ASP.NET

Reported on the community forum:

Two problems: both work fine using a normal textbox control. But neither works using the CKEditor control.

PROBLEM 2: I can't get character count using javascript (max char issue)

My code works on a normal textbox control, but doesn't with the CKEditor control. If you want to see the code, let me know.

Would be nice if you could provide reduced sample web-app / file showing the problem - something with what we will be able to reproduce the ticket using plain CKEditor for ASP.NET.

Hi, this first part demonstrates use of the code to prevent user from exceeding max char allowed. Max is set to 3. When user types fourth key in TextBox1, message pops up. This works.


<script type="text/javascript">

function Count(text,long) {

var maxlength = new Number(long);

if(document.getElementById('<%=TextBox1.ClientID%>').value.length > maxlength){

text.value = text.value.substring(0,maxlength); alert("Max " + long + " chars ..."); }



<asp:TextBox ID="TextBox1" runat="server" onKeyUp="javascript:Count(this,3);" onChange="javascript:Count(this,3);"

TextMode="MultiLine" Height="60" Width="200px"></asp:TextBox>


This next part tries to use the Script (same script) on the aspnet CKEditor control (instead of Textbox1). All I did was change the getElementById value. But it doesn't work.

I'm using aspnet CKEditor 3.6.2 in MS Web Developer 2010 Express. Browsers are Firefox, IE, Opera (all up to date versions).


<script type="text/javascript">

function Count(text,long) {

var maxlength = new Number(long);

if(document.getElementById('<%=CKEditor1.ClientID%>').value.length > maxlength){

text.value = text.value.substring(0,maxlength); alert("Max " + long + " chars ..."); }



<CKEditor:CKEditorControl ID="CKEditor1" runat="server"

onKeyUp="javascript:Count(this,3);" onChange="javascript:Count(this,3);" FontSizeSizes="8/8px;9/9px;10/10px;11/11px;12/12px;14/14px;" Width="450" Height="60" ToolbarFull="Bold|Italic|Underline|FontSize" ResizeMaxHeight="120" ResizeMaxWidth="450" UIColor="#FF9933" ></CKEditor:CKEditorControl>

Resolution: invalid
Status: newclosed

You are referring to CKEditor and not textbox so the below is invalid:


You should use CKEditor API to get data from it E.g. use getData() method (returns HTML) or perhaps using DOMApi.
The problem is that there is no method to simply get text from CKEditor user has to either get HTML and use regex on it or walk the DOM and get text from all the nodes (both sound slow)

As for the maxLength this is not supported by CKEditor Control - I have described this issue here #8936.

Closing this one as an invalid.
